Recombinase polymerase amplification: method’s characteristics and applications in diagnostics of infectious diseases

Abstract

Isothermal amplification techniques have been actively developed in recent years and are gradually introduced into the range of methods for infectious disease diagnostics. One of the fastest isothermal methods is recombinase polymerase amplification (RPA). This review contains information about the principle of RPA, the role of individual reaction components and primer design considerations. It provides information on characteristics of various methods of RPA results detection, effects of inhibitors, temperature and agitation on the efficiency of reaction. Approaches to quantitative and multiplex RPA are described, as well as some variants of portable devices designed to identify infectious agents. The conclusion summarizes advantages and disadvantages of RPA in comparison with other amplification methods.
